AUGUST IIIRSCIIEL, OF JERSEY CITY, NEV JERSEY, ASSIGNOR T() VILLIAM HENRY BOATVRIGIIT, OF NEV YORK, N. Y.

CHIlVlNEY-COWL.

SPECIFICATION forming part of Letters Patent No. 581,584, dated April 27, 1897.

Application liled March 14, 1895. Renewed February l0, 1897. Serial No. 622,869. (No model.)

T all whom t may concern:

Be it known that I, AUGUST IIIRSCHEL, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Chimney-Cowl, of which the following is a full, clear, and exact description.

My invention relates to an improvement in ehimney-cowls; and it has for its object to 1o provide a cowl which will be exceedingly simple, durable, and economic in its construction and one which will accommodate itself to the wind no matter in what direction it may be blowing.

struct al chimney-cowl having a conical and pivoted top in such a manner that the pivotal connection will be simply formed and will not wear to any material extent, and whereby, further, the conical cap may be lifted by the wind to a predetermined extent only, thus breaking the force of the wind should it get under the cap, and to provide also a detlector, forming a portion of the smoke-conducting pipe on the body of the cowl, in conjunction with which the conical cap will operate.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specificationvhich represents a central vertical section through a portion of the smoke-conducting pipe or body of a cowl, the improved cap be ing connected therewith.

In carrying out the invention the pipe A may be the upper end of a smoke-conducting pipe, or it may constitute the body portion of the cowl. The said pipe A is provided with a ilange 10, formed at its upper edge, which flange is shaped substantially as the frustum of a cone and extends outwardly and downwardly from the upper edge of the pipe or 45 body, surrounding the same.

Vithin the pipe or body usually two brackets 11 and 12 are located, and these two brackets are adapted as bearings for the lower portion of a spindle 13. The spindle is upright A further object of the invention is to conand extends a predetermined distance beyond the upper edge of the pipe or body A, being provided with a somewhat conical or rounded upper end. This spindle is adapted primarily as a support and pivot for the conical cap B. This cap is made preferably as light as possible consistent with strength, and at its apex a bearing 14 is firmly secured upon the inner side of the cap, which is made of tough glass, porcelain, china, or equivalent material, the said bearing being provided with a socket 'l5 in its lower face, of substantially conical formation, in which socket the pivot end of the spindle is made to enter.

Thus it will be observed that no matter to what extent the cap may be rotated or rocked upon the spindle the bearing thereof will practically not become worn, and the cap itself will be protected.

It is desirable that the cap should rise to a certain extent, but be prevented from rising to such a distance that the spindle can leave its bearings, since it is of great advantage at times to break the force of the wind by the yielding motion of the cap if the wind should eddy under the same. To this end chains or cables 1G, or the equivalents thereof, are attached either to the bearing 14 or to the inner face of the cap, and these chains are led downward around the spindle and connected with a ring 17, or its equivalent, loosely mounted upon the spindle, the said ring being prevented from traveling up the spindle beyond a predetermined distance by a collar, sleeve, or flange 18, produced on the spindle.

Thus in operation, no matter from what quarter the wind may blow, the conical cap will be tipped upon one side, that side presented to the wind, until its lower edge will come in engagement with the conical flange 10 of the body or pipe A. In this manner the wind will be eifectually prevented from entering the said body or pipe and will be defleeted to either side of the cowl, creating a proper draft. Then there is no wind, the cap will remain stationary, balanced upon its spindle 13, and the cap, together with the iiange 10, will effectually prevent the sun from shining into the body or pipe A, (since the sun tends to keep the gases in the chin1ney,) and Atherefore the gases will always have free exit. Furthermore, the flange 10 will serve to shed any water that may be driven against the upper portion of the pipe or body.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination with a pipe, and a spindle, secured to the pipe and projecting above the same, of a conical cap provided with a socket in its apex to receive the upper end of the spindle, a sliding ring on the spindle and having limited movement thereon, and a connection between the ring and cap, substantially as described.

2. The combination with a pipe, and a spindle secured in the pipe and projecting above the same, of a conical cap provided with a socket in its apeX to receive the end of the spindle, a ring loose on the spindle, chains secured to the cap and ring, and a stop on the spindle to limit the movement of the ring on the said spindle, substantially as described.

AUGUST HIRSCHEL.
